✅ Pathophysiology of Life-Threatening Odontogenic Infections
Most severe odontogenic infections originate from:

▪️ Untreated dental caries
▪️ Pulpal necrosis
▪️ Periodontal infections
▪️ Pericoronitis of third molars
The spread occurs through fascial spaces of the head and neck, facilitated by anatomical pathways and virulent polymicrobial flora dominated by anaerobic bacteria. Once deep cervical spaces are involved, the risk of systemic dissemination and airway compromise increases significantly.

✅ Clinical Warning Signs and Red Flags
Dentists must recognize early indicators of severe infection, including:
▪️ Rapidly progressing facial or cervical swelling
▪️ Trismus (limited mouth opening)
▪️ Dysphagia or odynophagia
▪️ Voice changes or drooling
▪️ Fever with systemic toxicity
▪️ Dyspnea or stridor
▪️ Elevated heart rate and hypotension
These findings may indicate involvement of critical spaces such as the submandibular, sublingual, parapharyngeal, or retropharyngeal spaces, commonly associated with Ludwig’s angina and other deep neck infections.

Night Guards for Bruxism: A Complete Dental Guide for Symptom Prevention and Control

Bruxism is a condition in which a person grinds or clenches their teeth, often without noticing it. It usually happens during sleep but can also occur while awake. Many people are surprised to learn that night guards do not treat bruxism itself.

📌 Recommended Article :

Dental Article 🔽 Night Guards: Do They Really Help with Bruxism? ... However, an important clinical question remains: do night guards truly help manage bruxism, or do they simply protect the teeth from its consequences?

Instead, they are designed to protect the teeth and jaw from the damage caused by bruxism. This guide explains, in simple terms, how night guards work, what they can and cannot do, and why they are an important part of symptom control—not a cure.

Advertisement

✅ What Is Bruxism?
Bruxism is a repetitive jaw activity involving tooth grinding or clenching. It is now understood as a condition related to the brain and nervous system, not a problem caused by how the teeth fit together.

Common factors linked to bruxism include:
▪️ Stress and emotional tension
▪️ Sleep disturbances
▪️ Anxiety or concentration habits
▪️ Certain medications
Because bruxism starts in the brain, there is no device that can completely stop it.

📌 Recommended Article :

Dental Article 🔽 Bruxism in Children vs. Adults: Key Differences, Risks, and Evidence-Based Treatments ... Emerging evidence links bruxism, especially sleep bruxism, to neurophysiological arousal and sleep disturbances, highlighting the need for interdisciplinary evaluation.

✅ What Are Night Guards and How Do They Work?
Night guards (also called occlusal splints) are removable dental appliances worn during sleep. They are usually made of acrylic or flexible materials and are custom-made by a dentist.

Their main function is to:
▪️ Create a protective barrier between the teeth
▪️ Reduce pressure on teeth and jaw joints
▪️ Limit muscle overload during clenching
It is important to understand that night guards do not eliminate bruxism. They simply contain its harmful effects.

📌 Recommended Article :

Dental Article 🔽 Occlusal Splints: Types, Benefits, and Who Needs Them ... Occlusal splints are essential devices for protecting teeth, managing jaw disorders, and preventing long-term dental complications.

▪️ Lower the risk of tooth fractures
▪️ Reduce jaw muscle discomfort
▪️ Help prevent damage to dental restorations

What They Cannot Do
▪️ Stop tooth grinding
▪️ Treat the neurological cause of bruxism
▪️ Replace stress or sleep management
This distinction is essential for setting realistic expectations.

📌 Recommended Article :

Dental Article 🔽 Bruxism - A Major Cause of Gum Recession ... The unconscious and nocturnal act of grinding or clenching the teeth is known as bruxism. This pathology is the cause of wear or fractures of the teeth or dental prostheses.

💬 Discussion
Night guards are often misunderstood as a treatment for bruxism. Scientific evidence shows that they act as protective tools, not curative solutions. Their value lies in preventing long-term damage, especially to teeth, muscles, and jaw joints. For best results, night guards should be used as part of a broader approach, which may include stress reduction, sleep improvement, and regular dental follow-up.

✍️ Conclusion
Night guards play a crucial role in protecting oral structures from the consequences of bruxism, but they do not cure the condition. When patients understand their real purpose, night guards become a safe and effective way to control symptoms and preserve oral health over time.

✅ ADA and CDC Clinical Guidelines

Indications for Antibiotic Use
The ADA and CDC recommend antibiotic therapy in pediatric dental patients only when:
▪️ There is systemic involvement (fever, malaise).
▪️ Evidence of spreading infection (cellulitis, deep space infection).
▪️ The child is immunocompromised or medically complex.

Situations Where Antibiotics Are Not Recommended
Antibiotics are not indicated for:
▪️ Irreversible pulpitis without systemic signs.
▪️ Localized dental abscess with adequate drainage.
▪️ Pain management in the absence of infection.

📌 Recommended Article :

Dental Article 🔽 Dental Abscesses in Primary Teeth: Evidence-Based Management in 2025 ... This article reviews evidence-based approaches (2025) for diagnosis, management, and prevention, highlighting the importance of early intervention to preserve oral and general health.

✅ Commonly Recommended Antibiotics
When antibiotics are justified, amoxicillin remains the first-line agent due to its efficacy, safety profile, and narrow spectrum. In cases of penicillin allergy, alternatives such as clindamycin or azithromycin may be considered, although increasing resistance patterns warrant cautious use.

💬 Discussion
The implementation of antibiotic stewardship programs in pediatric dentistry requires continuous education, adherence to clinical guidelines, and effective communication with caregivers. Studies consistently demonstrate that reducing unnecessary antibiotic prescriptions does not increase treatment failures but significantly decreases adverse events and resistance risk. The ADA and CDC emphasize that dentists play a pivotal role in combating AMR by adopting evidence-based prescribing behaviors and prioritizing local dental treatment over systemic medication.

📌 Recommended Article :

Dental Article 🔽 Periapical Abscess vs Periodontal Abscess: Key Differences, Similarities, and Treatments ... Dental abscesses represent one of the most common acute infections in dentistry. Among them, the periapical abscess and the periodontal abscess are distinct entities with overlapping clinical features, which often complicates diagnosis.

✍️ Conclusion
Antibiotic stewardship in pediatric dentistry is essential to ensure patient safety, preserve antibiotic efficacy, and reduce antimicrobial resistance. Adherence to ADA and CDC recommendations supports judicious antibiotic use, reinforces the importance of definitive dental treatment, and aligns pediatric dental care with global public health priorities.

🎯 Clinical Recommendations
▪️ Avoid prescribing antibiotics for localized dental infections without systemic involvement.
▪️ Prioritize definitive dental treatment over pharmacological management.
▪️ Use narrow-spectrum antibiotics when indicated and for the shortest effective duration.
▪️ Educate parents and caregivers about the risks of unnecessary antibiotic use.
▪️ Maintain updated knowledge of ADA and CDC clinical guidelines.

📊 Comparative Table: ADA & CDC Antibiotic Stewardship Principles in Pediatric Dentistry

Pulpotomy Materials Comparison: Calcium Hydroxide vs. Mineral Trioxide Aggregate (MTA) in Primary Molars

Pulpotomy is a widely accepted vital pulp therapy for primary molars affected by carious exposure or traumatic injury, aiming to preserve the radicular pulp and maintain tooth function until natural exfoliation.

📌 Recommended Article :

Video 🔽 Video: Pulpotomy of Deciduous Molar - Step by step ... This article provides a comprehensive, step-by-step overview of the pulpotomy procedure in deciduous molars, a vital technique in pediatric dentistry aimed at preserving pulp vitality after carious exposure.

The selection of an appropriate pulpotomy material is critical, as it directly influences clinical success, pulpal healing, and long-term prognosis. Among the materials most frequently studied, calcium hydroxide (CH) and mineral trioxide aggregate (MTA) have received significant attention due to their biological properties and historical relevance.

Advertisement

This article provides an updated and evidence-based comparison of these two materials, emphasizing their performance in primary molar pulpotomy from a contemporary pediatric dentistry perspective.

✅ Biological Rationale of Pulpotomy Materials

Calcium Hydroxide
Calcium hydroxide has been traditionally used in vital pulp therapy due to its high alkalinity, antibacterial effect, and ability to stimulate reparative dentin formation. However, its application in primary teeth has shown limitations, including internal resorption and incomplete dentinal bridge formation, which may compromise treatment outcomes.

Mineral Trioxide Aggregate (MTA)
MTA is a bioactive calcium silicate-based material known for its excellent biocompatibility, sealing ability, and capacity to induce hard tissue formation. In primary molars, MTA promotes favorable pulpal responses, including reduced inflammation and consistent dentin bridge formation, contributing to higher long-term success rates.

📌 Recommended Article :

Dental Article 🔽 Calcium Hydroxide in Pediatric Dentistry: Benefits and Limitations ... In pediatric dentistry, calcium hydroxide is used primarily for vital pulp therapy procedures such as direct pulp capping, pulpotomy, and apexogenesis.

✅ Clinical and Radiographic Outcomes
Multiple randomized clinical trials and systematic reviews have demonstrated that MTA exhibits superior clinical and radiographic success compared to calcium hydroxide in primary molar pulpotomy. While CH may provide acceptable short-term outcomes, MTA consistently shows lower rates of pathological root resorption, pulp necrosis, and treatment failure during follow-up periods extending beyond 12 months.

💬 Discussion
The declining use of calcium hydroxide in primary molar pulpotomy is supported by growing evidence highlighting its biological instability in primary pulp tissue. In contrast, MTA has emerged as the reference material due to its predictable healing response and long-term effectiveness. Despite its higher cost and handling complexity, MTA’s advantages outweigh these limitations, particularly in pediatric patients where preservation of primary teeth is essential for occlusal development and space maintenance.

✍️ Conclusion
Based on current scientific evidence, mineral trioxide aggregate demonstrates superior clinical performance compared to calcium hydroxide in pulpotomy of primary molars. Its enhanced biocompatibility, sealing properties, and reduced risk of internal resorption make MTA the preferred material for vital pulp therapy in primary dentition.

🎯 Clinical Recommendations
▪️ MTA should be considered the material of choice for pulpotomy in primary molars when available.
▪️ Calcium hydroxide should be used with caution due to its association with internal resorption and lower long-term success.
▪️ Proper case selection, hemorrhage control, and coronal sealing remain critical regardless of the material used.
▪️ Long-term clinical and radiographic follow-up is essential to evaluate pulpal response and tooth integrity.

📊 Comparative Table: Calcium Hydroxide vs. MTA in Primary Molar Pulpotomy

Clinical Parameter	Calcium Hydroxide	Mineral Trioxide Aggregate (MTA)
Biocompatibility	Moderate; may induce chronic inflammation	Excellent; promotes favorable pulpal healing
Dentin bridge formation	Inconsistent and porous	Homogeneous and well-organized
Risk of internal resorption	High incidence reported	Minimal to none
Long-term clinical success	Lower success rates over time	High success rates in long-term follow-up
